"Vault" matching MCP servers:

An MCP server that lets Claude Code search Google Drive, read vault notes, and pull Drive files into the vault using rclone authentication. It operates with read-only scope and supports document section filtering.

Discover, archive, catalog, and verify OpenCode sessions with remote upload support.

An MCP server that enables AI assistants to search, read, and manage files across multiple cloud drives (Baidu, Aliyun, 115, OneDrive, Quark) through a unified interface.

Enables Claude to read, write, search, and manage Obsidian vault notes through a serverless MCP server deployed on Cloudflare Workers and R2 storage, utilizing Obsidian Sync for seamless bidirectional synchronization without requiring local NAS or tunnel infrastructure.

Zero-knowledge document vault backed by Azure Blob Storage with built-in MCP server. Client-side AES-256-GCM encryption, five tools (list, get, search, create, update), and OAuth-gated access for Claude.

Zero-Knowledge Cloud Drive for Humans and Agents. Client-side AES-256-GCM encryption with 7 MCP tools for secure file vault management — the server never sees plaintext data.

A Model Context Protocol server that enables Claude to list, read, write, create, delete, and search files on a self-hosted Nextcloud instance via WebDAV, with additional Obsidian vault-aware operations for frontmatter, tags, backlinks, and wikilinks.

Enables an AI agent to discover, read, create, patch, append, move, and inspect the revision history of Markdown notes in an Obsidian vault synced through Google Drive, with optimistic concurrency and optional trash-based deletion. It works directly against Drive-side vault storage without requiring Obsidian, rclone, or a second vault copy.

Remote-capable MCP server that reads and writes Markdown notes in an Obsidian vault on OneDrive via Microsoft Graph, enabling creation even when the PC is offline.
